MEANS FOR STORING AND .HANDLING PETRGLEUlVl-OIL.

SPECIFICATION forming part of Letters Patent No. 444,731, dated January 13, 1891.

Application filed January 19, 1889. Serial No. 296,946. (No model.)

To all whom, it may concern,.-

Beitknown that I, LUTHER C. SNELL, a citizen of the United States, residing at Detroit, in the county of lVayne and State of Michigan, have invented certain new Vand useful Improvements in Means for Storing and Hand ling Petroleuni-0il, of which the following is a specification.

This invention relates to new and useful improvements in means for storing and handling all gra-des of petroleum without odor or loss from evaporation; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it belongs to make and use it, reference being had to the accompanying drawings, which form a part of this specification.

The primary object of my invention is to improve the storing and handling of petroleum in buildings where it is used as fuel, and provide suitable means for elevating` it and supplying it to the burner with a uniform pressure.

To this end my invention consists in displacing the oil through the top of the tank by introducing water under iiXed pressure derived from any convenient source, such as the city water-pipes, or from any elevated water-supply.

My invention .further consists in the construction and arrangement of an apparatus showing a specific application of my invention to an ordinary dwelling for supplying it with liquid fuel for heating or cooking, all as more fully hereinafter described.

In the drawings which accompany this specification, Figure lis a diagram elevation showing my invention as applied for using crude oil or other liquid hydrocarbon for fuel in a dwelling. Fig. 2 is a detached vertical section of the warming device. Fig. 3 is a vertical section of a storageetank full of water and ready to be filled with oil. Fig. et is a similar view showing the tank after being iilled with oil.

Similar letters refer to similar parts th roughout the several views.

A is the storagetank.

B is the pipe which conveys the oil from the wagon, car, pipe-line, or other source of supply into the storage-tank. rIhis pipe discharges the oil at or near the top of the tank, and with the discharge opening or openings D so arranged that the oil will be discharged in a horizontal direction, in order to prevent it from diving down into the water. lNhen the pipe enters the tank horizontally, the dis charge is in the end of the pipe. Thepipe is provided with a valve C, and an air-tight joint must be ina-de around the pipe where it passes through the wall or top of the tank, and an air-tight coupling must be used in joining pipe B to tank wagon, car, or pipe-line. so that no air can be sucked in with the oil.

B represents a branch pipe having a nozzle-coupling .I on its end. It extends out from the pipe B near the tank, and may be n employed as a discharge-pipe for the oil when the same is to be utilized for other purposes than those described.

In lieu ot valve C a hosecoupling with l1osecap can be used on outer end of pipe B B. In that case it is necessary to close the valves X and K and open valve G until the pressure on the hose-cap is relieved before the hosecap is removed to do t-he coupling.

V is a waterfserviee pipe.

R is a stand-pipe open on top and con-` nected to the servieepipe.

X is a valve in the standpipe, and T is an overflow-pipe from the top of the stand-pipe.

F is a pipe through which the water is forced into the bottom ot' the tank A from the standpipe R, with which it is suitably connected by the pipe H. The discharge-opening E of this pipe is also suit-ably arranged to cause the water when Iiowing into or out of the tank to l'low in a horizontal direction, so as to prevent it from disturbing the contents of the tank.

The pipe F is provided with a suitable dis charge-opening outside the tank, through which the water maybe discharged from the tank, and this is controlled by a suitable waste-valve G.

I is the pipe through which the oil is elevat-ed from the tank A to the place where it is desired to be used for fuel or otherwise and having a valve K therein.

As the principal object of my invention is to store and handle petroleum when it is to be used in buildings for' heating or cooking, I will further describe and show the connec- IOC tion of my apparatus with a cook-stove, which in the drawings is represented as being located on the ground floorof a building, while the storage-tank is supposed to be in the cellar or under ground, using such modifications of the tank as adapted to the circumstances. The pipe I, through which the oil is elevated from the storage-tank, as will be hereinafter more fully described, carries the oil to the burner of the stove, the quantity of feed being regulated by a suitable valve orvalves in said pipe. At some point an enlargement or chamber is formed by means of a suitable vessel O, into which the separated ends of the pipe I project some distance below the top and above the bottom, respectively, `forming thereby a trap for retaining scum which floats on top and impurities which may settle on the bottom, a valve N being arranged to draw off the contents of the vessel. By placing this vessel close to the back of the stove the contents are warmed, and thereby rendered more fluid, so as to tiow easier through the valves and burner and be purified more readily. Astrainer M is preferably placed over the exit-opening of the pipe I from the vessel O. If the burner is of the kind requiring a small supply of Water to be converted into steam for the smokeless combustion of the oil, I preferably allow the overflow from the pipe T to flow in a cup S, from which a pipe U carries the necessary amount of water to the vthrough an overfiow-pipe IV.

The parts being constructed as described and shown, the operation is as follows: To fill the tank with oil for the rst time, close valve K in the feed-pipe I, open valve C, and allow the tank to till with Water from the standpipe by opening valve X. When the storagetank is full of water, close valve C and X and make the coupling between the pipe b and the wagon-tank, car-tank, or pipe-line from which the storage-tank is to be filled, open valve C in pipe B, and then open valve G and let the Water run out until oil appears, which indicates that the tank is filled. Then closeV valves C and G, and the Wagon-tank may be uncoupled. A glass indicator may be placed on the outside of the storage-tank, if desired, to show the quantityof oil. in the tank at any time. If the valve X is now opened, the oil will be elevated in the pipe I to a height corresponding to the hydraulicv pressure of the water in the stand-pipe, and it the pipe I is tapped at any point below, the oil will tlow out and the amount of flow may be regulated by the size or degree of opening of the valve X, and a proportionate amount of water will displace the oil inthe tank until all of the oil is elevated. In practice-the valve X in the supply-pipe is opened a little more than the valve K in the pipe I. This keeps the standpipe always full to the top and insures uniform fixed pressure upon the oil, no matter how the pressure in the service-pipe may vary, and at the same time a sufficient overflow is produced into the cup S to furnish the necessary amount ofi' water to the stoves through the pipe U to supply the burner with steam. After all the oil is fed to the burner the tank may be relled with oilwithout first filling it with water, as before described, as the tank is now already filled With it.

A suitable air valve or valves should be placed at convenient points for the purpose of permitting the system of pipes, tank, andv vessel O to be drained, if necessary, to remove the sediment or scum accumulated.

That I claim as my invention is l. The combination, with a storage-tank having at its lowei1 end a valved connection, with a water-supply under pressure and a valved discharge-pipe at its bottom, of an oilsupply having a lateral discharge-opening Within the tank and an oil-discharge pipe at the top of the tank, substantially as described.

2. The combination, with a storage-tank having at its lower end a valved connection, with a water-supply under pressure and' a discharge-pipe at its bottom, of an oil-supply and a discharge-pipe at its top, a burner into which the oil-discharge enters, a stand-pipe connecting with the water-supply and an overflow-pipe, and a connection with the overflow-pipe at a point at or above the level of the burner, extended to and connected with the burner, substantially as described.

LUTHER C. SNELL.
